Nation View: Ugly face of caste system in India

A cab driver was beaten up allegedly by a group of Africans in the wee hours today in south Delhi's Rajpur Khurd, the locality in which African nationals were attacked by groups of locals in four separate incidents last week. President Pranab Mukherjee today expressed concern over a string of alleged attacks on Africans in the country, saying it would be most unfortunate if the people of India were to "dilute our long tradition of friendship with the people of Africa".
